Fundamentals of Measurement Uncertainty

Course ID FMU
Format Face-to-Face

Learn about measurement uncertainty for both testing and calibration laboratories.

Learn a practical approach to measurement uncertainty (MU) applications, based on fundamental practices. Hear about MU for both testing and calibration laboratories and understand the steps required, accepted practices, and the types of uncertainties that need to be considered by an accredited laboratory.
